@piyush286 - please add a license at the top of these files, as we do with other xml files (example: https://github.com/AdoptOpenJDK/openjdk-tests/blob/master/openjdk_regression/playlist.xml#L2-L14)

@smlambert Thanks! Added those license headers! Btw just wondering whether we need to add those headers to all our other files. I guess it's just good practice to mention the license info.

Looking at this openjdk-test-tools repo, we just have 35 files, mainly xml, with those headers while over 250 files of all types on the openjdk-tests repo.

Yes, typically all files should have the Apache V2 license in the header, if they are destined for AdoptOpenJDK repos. There may a few file types that we do not bother to do so, but generally all.

Format differs slightly depending on what type the file is (xml vs java vs other languages), can look in the other AdoptOpenJDK repos, as you have done to find examples for most file types.

In a separate PR we can update some additional files in this repo, do not worry about it as part of this PR.
